BACKGROUND

Obstruction of the upper airway by the tongue is a common complicationwhen a sedated or unconscious patient is lying in the supine position.The causes of unconsciousness may be sedation, anesthesia, head trauma,drug overdose or any of a multitude of medical causes. The patient maybe in any emergency situation. The direct cause is that gravity pullsthe person's tongue downwards (towards the cervical spine) and thetongue obstructs the airway and impedes respiration, partially orcompletely. The airway obstruction discussed above might cause alife-threatening situation if the airway obstruction is not urgentlycleared, for hypoxemia and death can quickly ensue.

Anesthesiologists commonly overcome airway obstruction by tilting thepatient's head backwards and pulling the chin up towards the ceiling andaway from the body (cephalad). Obstruction of the airway is overcomebecause the base of the tongue is attached to the mandible, and bypulling the chin upward the tongue will be simultaneously pulled upward.This practice is very fatiguing and restricts the anesthesiologist's oremergency responder's ability to perform other functions that requiretwo free hands.

An upper airway can also be maintained open by inserting various medicaltubes into the airway, for example, nasal-pharyngeal, oral-pharyngeal,laryngeal mask airway (LMA) and the cuffed oral pharyngeal. But as oftoday, there are no medical devices in common use that attach externallyto the face that will maintain an open upper airway.

In the past, medical personnel have attempted to use surgical tape toattempt to maintain an open upper airway. Anesthesiologist would securetape around the chin of a patient and then attach the ends of the tapeto an operating room table. Tape procedures are unsatisfactory, for thetape attachment pulls back and downwards and do not provide the upwardpull required on the chin to maintain an open upper airway. Tape quicklystretches and traction is lost. Tape is not sufficiently adherent tocope with the traction forces and detaches. Other complications withthis procedure are skin trauma and eye damage. The tape passes close tothe patient's eyes and contact with the eye is unavoidable if thepatient coughs or turns the head. The method of attaching tape to theoperating room table cannot be used to manage an obstructed airwayoutside of the operating room, example, at a roadside motor vehicleaccident or during subsequent transportation to hospital.

Chin props comprising a ball on the end of an arm secured to theoperating room table have also been used to push the chin up. They toohave proven to be unsatisfactory and are not commonly used, because theyare large and cumbersome and get in the way of surgeons operating on theupper body. Furthermore, if misapplied they may constrict the airway.Chin props with complex mechanisms that attach to suitable operatingtables, cannot be used to manage an obstructed airway outside of theoperating room, for example, at a roadside motor vehicle accident orduring subsequent transportation to hospital.

Information relevant to attempts to address these problems can be foundin U.S. Pat. Nos. 5,494,048, 6,200,285 B1, and 6,196,224 B1. However,each one of these references suffers from one or more of the followingdisadvantages:

-   1. Can cause eye damage and skin trauma;-   2. Require attachment to suitable operating tables;-   3. Obstruct the attendant's view of the patient;-   4. Do not provide sufficient upward leverage to the chin;-   5. Do not lend themselves to use in accident situations;-   6. Do not effectively overcome airway obstruction; and-   7. Difficulties in removal of devices, should immediate endotracheal    intubation be required.

Inside and outside the operating room, an urgent need exists forequipment that overcomes upper airway obstruction and maintains an openupper airway. This equipment should be compatible with and improve theeffectiveness of oral-pharyngeal and nasal-pharyngeal airways and facemasks. In the operating room, such equipment would allow mask anesthesiato be used for sedated and anesthetized patients instead of generalanesthesia and endotracheal intubation with immediate cost savings.Outside the operating room, a need exists for portable, compactequipment that can overcome upper airway obstruction and maintain anopen airway and that can be used in cramped quarters such as anambulance, a hyperbaric chamber and an MRI chamber.

For the foregoing reasons, there is a need for a medical device is safeand reliable that will overcome upper airway obstruction and that willmaintain an open airway in the anesthetized and sedated patient lying ina supine position in an operating room and any unconscious patient lyingin the supine position at any site. To be effective, the equipmentshould be safe and easy to use and reliable. The equipment should freeup the operators' hands; render oral and nasal pharyngeal airways moreeffective and not interfere with but facilitate the use of a face mask.The equipment should be free standing, compact and portable.

SUMMARY

The present invention is directed to a medical device that assists inovercoming airway obstruction and maintaining an open airway when apatient, who may or may not be anesthetized, is unconscious and placedin the supine position. This device satisfies the following needs:

-   1. It frees the practitioner's hands to do other tasks;-   2. Does not obstruct the view and allows the practitioner to    visually monitor the patient;-   3. It is a compact and portable device;-   4. It does not cause eye damage or skin trauma;-   5. Does not require the use of specific operating room tables when    operating the device; and-   6. Allows for the easy removal of the device should the patient    vomit or emergency endotracheal intubation be required.

The medical device for overcoming airway obstruction comprises of arectangular cradle that has first and second portions, wherein the firstportion has a length that is at least a distance that allows a patient'shead to rest on and act as an anchor to the cradle and the secondportion has a length that is at least a distance that allows a band tobe placed under a patient's chin and encircle the second portion so thatan upward pull can be generated on the chin by the band when the secondportion is placed in a perpendicular position to the first portion, andthe cradle's width is at least a distance that allows for the clearanceof a patient's side facial features when the patient's head rests on thefirst portion of the cradle and a band is made to encircle the chin of apatient and attach to the second portion of the cradle; and a band thatattaches to the second portion of the cradle when the second portion isperpendicular to the first portion.

One of the many advantages of this invention is the simplicity of itsconstruction. The fact that the two main elements of this invention area perpendicular portions and a band that can be easy attached to one ofthe portions of the plate after encircling the chin of a patient whosehead rests on the other portion of the cradle after being placed in asupine position, attest to the simplicity of construction and use ofthis device. This invention takes precautions in preventing injuriesthat have been previously caused by the prior art, for example, eyedamage or skin trauma. This invention also aids those in the emergencytransportation field, for they need to have the maximum use of theirhands when dealing with other aspects of emergency situations facingthem. In addition, not having to worry whether the patient is breathingproperly can allow emergency personnel to care for other injuriessustained by the patient and to attend to other patients.

A further advantage to this invention is that it is a stand-alonemedical device. The device does not need to be attached to anysupporting devices to become operable. When a patient's head is made torest on one of the surfaces of the perpendicular portion, the weight ofthe patient's head on the portion is sufficient to secure the cradle sothat an upward pull on the chin created between a band attached to thesides of the cradle not carrying the weight of the patient's head andthe patient's chin will be maintained during the use of this device.Remember, as long as this upward pull is maintained, the upper airwaywill be maintained open, thus it is key that the tension created withthis device not be compromised and this is easily solved by using theweight of the patient's head as the anchor to the device.

Yet another advantage to this invention is the placement of the band onthe second portion insures that the band does not come in contact withthe patient's eyes, this is very important for one cannot preventcoughing and other involuntary movements of the head.

The length of the first portion 12 should be atleast of a length that will allow a patients head to rest on it and actas an anchor to the medical device. The length of the second portion 14should be of at least of a length that will create an upward pull on thechin of a patient when a band 16 is made to encircle the chin of thepatient, when a patient is placed in a supine position, and the secondportion 14 of the cradle 10. In a preferred embodiment of the invention,the length of the portions will be eight inches to twelve inches.Another embodiment of the invention has the first 12 and second 14portions of the cradles being both eight inches in length. The width ofthe portions is to be at least eight inches, the preferred embodimentwould have a width of twelve inches. The width has to be of sufficientlength to allow for the clearance of the eyes when attaching the band 16to the second portion 14 of the portion 10. As seen in FIG. 2 and FIG.3, the second portion 14 of the cradle can define an aperture 14 a thatwill merely make the second portion of the cradles a physical skeletonto attach the band 16 or straps yet to be defined.

The band can be made of an elastic material that has a degree of tensionsufficient to pull the weight of a person's chin upward (when thepatient is placed in a supine position) when encircling the secondportion of the cradle and the chin of the patient. As seen in FIG. 2,the band 16 can also be made of fabric and have two ends, if the band 16is made of fabric, then it is preferable that the ends of the bands 16ahave either hook or pile fasteners. When using a fabric band 16, it isessential that the second portion 14 of the cradle have two receivingmeans 22 located on opposite sides of the second portion 14 and runningalong the length of the second portion 14 and situated a sufficientheight to allow for an upward pull to be generated on the chin of apatient when the band 16 is placed around the chin of the patient andthe ends of the band 16 a are attached to receiving means 22 of thesecond portion 14 of the cradle. The receiving means 22 will alsocomprise of either hook or pile fasteners, depending on what typefasteners the ends of the band 16 a utilize.
